Payment by Invoice for PrestaShop (payment gateway)

How Does the Module Work?

1. The customer creates an order and selects the "Invoice Payment" method.
2. The module automatically sets the order status to "Invoice Payment" and sends an email with relevant information to the customer.
3. When the merchant verifies the payment for the goods, they manually change the order status to "Payment Received".

Frequently Asked Questions about Module Operation

I have PrestaShop 1.7.x, and the module translations do not appear. How can I fix this?
Answer: Go to the module folder: /modules/cm_invoicepay/translations/en-US/
Copy the XLF files to the folder: /app/Resources/translations/en-US/
If necessary, repeat the process for other languages. Finally, clear the PrestaShop cache to load the translations.

In the final step of the payment process, a message indicates that an email template is missing. How can I fix this?
Answer: Please go to: Admin Panel » Orders » Order Statuses. Edit the "Invoice Payment" status and check if the email template cm_invoicepay_awaiting.html is correctly assigned for all enabled languages. If you do not find the email template with this name in the available list, copy it from the module folder to the /mails/<language>/ folder. Then repeat the template selection process in the order status.

Important: The problem may also occur if you intend to use the module in a language other than Slovak, Czech, or English. In this case, in addition to localizing the module itself into the appropriate language, it is necessary to create the cm_invoicepay_awaiting.html (.txt) email templates in that language.
